Class Mechanize::Page::Meta
In: lib/mechanize/page/meta.rb
Parent: Link

This class encapsulates a Meta tag. Mechanize treats meta tags just like ‘a’ tags. Meta objects will contain links, but most likely will have no text.

Methods

parse  

Constants

CONTENT_REGEXP = /^\s*(\d+\.?\d*)(;|;\s*url=\s*['"]?(\S*?)['"]?)?\s*$/i   Matches the content attribute of a meta tag. After the match:
  $1:: delay
  $3:: url

Public Class methods

Parses the delay and url from the content attribute of a meta tag. Parse requires the uri of the current page to infer a url when no url is specified. If a block is given, the parsed delay and url will be passed to it for further processing.

Returns nil if the delay and url cannot be parsed.

  # <meta http-equiv="refresh" content="5;url=http://example.com/" />
  uri = URI.parse('http://current.com/')

  Meta.parse("5;url=http://example.com/", uri)  # => ['5', 'http://example.com/']
  Meta.parse("5;url=", uri)                     # => ['5', 'http://current.com/']
  Meta.parse("5", uri)                          # => ['5', 'http://current.com/']
  Meta.parse("invalid content", uri)            # => nil
